RMA Companies acquires Earth Engineers

RMA Companies, a Los Angeles-based geotechnical engineering and environmental consulting firm, has acquired Earth Engineers, a Camas, Washington-based geotechnical engineering firm.

Founded in 2006, Earth Engineers delivers geotechnical, geologic, and construction materials testing and inspection services for municipal, residential, industrial, and commercial construction projects. The firm’s areas of expertise include pavement evaluation and design, foundation and retaining wall design, seismic studies, geologic and geotechnical assessments, and slope stability evaluation.

Earth Engineers has 24 employees listed on LinkedIn and has offices in Camas, Washington; Springfield, Oregon, and Aiea, Hawaii.

RMA’s acquisition of the boutique firm will broaden its Pacific Northwest footprint to six offices and laboratories. The deal builds on RMA’s acquisition of Portland-based Northwest Geotech in December 2022.

“This is an exciting period for RMA and our new colleagues at Earth Engineers,” said Ed Lyon, CEO of RMA. “Our organizations have aligned business values, including a shared commitment to technical excellence and client service. Earth Engineers enhances RMA’s strategic and geographic positioning, fortifying our service offerings to better serve our existing and prospective clients with efficient and comprehensive solutions.”

RMA in February acquired geotechnical consultancies Black Eagle Consulting (Reno, Nevada) and Insight Group (Charleston, South Carolina). In December, the firm expanded into Texas and Kansas with the purchase of Rone Engineering.

RMA has executed a steady pace of bolt-on deals since it was acquired by OceanSound Partners in September 2021.

“We are thrilled to join the RMA family of companies,” said Troy Hull, founder and president, Earth Engineers. “This new phase of growth will broaden our service offerings, enhance our capacity for work, and extend our geographic reach.”
